Description

Channel sending method, receiving method, device, network element and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on April 3, 2024, with application number 202410403752.6 and application name “Channel Transmitting Method, Receiving Method, Device, Network Element and Equipment,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a channel sending method, receiving method, apparatus, network element, and equipment. Background Art

[0003] To support the interconnection of hundreds of billions of devices and address the high network construction costs associated with large-scale IoE deployment, as well as the high operational costs associated with subsequent maintenance, such as battery replacement, a new type of Internet of Things (IoT) device is being designed within the 5G New Radio Access (NR) system: Ambient IoT (A-IoT). A-IoT devices have limited or no energy storage capabilities and are characterized by low complexity, low cost, and low power consumption, contributing to the realization of the perception and interconnection of everything.

[0004] In a 5G NR A-IoT communication system, different types of A-IoT devices with different capabilities may coexist. Currently, A-IoT devices can be divided into the following two types:

[0005] Type 1 devices: Peak power consumption is approximately 1 μW, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10 X ppm, the device has neither downlink nor uplink amplification capabilities. The device's uplink transmission is backscattered on an externally provided carrier.

[0006] Type II devices: peak power consumption ≤ several hundred μW, with energy storage capability, and initial sampling frequency offset (SFO) up to 10 X ppm, the device has downlink and / or uplink amplification capabilities. The device's uplink transmission can be generated internally by the device or backscattered on an externally provided carrier.

[0431] By adopting the fifth format or type design for sending or receiving long messages, the target channel format or type field can be used to indicate that the target channel is a long message, thereby facilitating the device to receive the long message.

[0432] In one implementation, when the target channel includes two formats or types, the target channel includes:

[0433] a first format or type and a second format or type; or,

[0434] a first format or type and a third format or type; or,

[0435] a second format or type and a third format or type; or,

[0436] a fourth format or type and a fifth format or type.

[0437] In another implementation, when the target channel includes three formats or types, the target channel includes:

[0438] a first format or type, a second format or type, and a third format or type; or,

[0439] a first format or type, a fourth format or type, and a fifth format or type.

[0440] In yet another implementation, when the target channel includes four formats or types, the target channel includes:

[0441] a first format or type, a second format or type, a fourth format or type, and a fifth format or type; or,

[0442] a first format or type, a third format or type, a fourth format or type, and a fifth format or type.

[0443] In summary, in the embodiment of the present disclosure, the device receives a target channel sent by the first network element, and the target channel includes at least one of the following formats or types: a first format or type for sending or receiving system information; a second format or type for sending or receiving control information; a third format or type for sending or receiving data information; a fourth format or type for sending or receiving short messages; a fifth format or type for sending or receiving long messages; using this method, the first network element can send target channels of different formats or types to different types of A-IoT devices with different capabilities, so that one channel is compatible with multiple information such as system information, control information or data information, and is also compatible with first type devices and second type devices, which can allow low-complexity first type devices to complete basic operations, and high-complexity second type devices to complete more operations. At the same time, one channel can also adapt to multiple application scenarios, thereby simplifying system design, reducing device complexity and cost, and saving device power consumption.

[0444] In order to more clearly describe the channel sending method and receiving method provided by the embodiments of the present disclosure, the target channel is described below with reference to several examples.

[0445] Example 1: The target channel carries information in the preamble

[0446] The first network element sends a target channel to the device, where the target channel includes at least one of the following formats or types:

[0447] a first format or type for sending or receiving system information;

[0448] a second format or type for controlling the transmission or reception of information;

[0449] a third format or type for transmitting or receiving data information;

[0450] A fourth format or type for sending or receiving short messages;

[0451] A fifth format or type used for sending or receiving long messages.

[0452] In this example, specifically:

[0453] In addition to being used for synchronization, the preamble in the target channel can also be used to activate or deactivate the device. Upon receiving the preamble from the first network element, the device first determines whether the preamble is intended to activate itself. If so, it uses the preamble to complete synchronization and subsequently receive the remaining fields of the target channel. It then determines whether the preamble is intended to deactivate itself. If so, the device directly enters the deactivated state.

[0454] The preamble in the target channel can activate or deactivate a device, a group of devices, a class of devices, or all devices. This includes:

[0455] Specific preamble sequence 1 is used for activation of all devices, and specific preamble sequence 2 is used for deactivation of all devices.

[0456] Specific preamble sequence 3 is used to activate the first group of devices, and specific preamble sequence 4 is used to activate the second group of devices.

[0457] The specific preamble sequence 5 is used to deactivate the first group of devices, and the specific preamble sequence 6 is used to deactivate the second group of devices.

[0458] The specific preamble sequence 7 is used to activate the first category of devices, and the specific preamble sequence 8 is used to activate the second category of devices.

[0459] The specific preamble sequence 9 is used to deactivate the first category of devices, and the specific preamble sequence 10 is used to deactivate the second category of devices.

[0460] As shown in Figure 9, the specific process is as follows:

[0461] The first network element determines to activate devices in group 1 and deactivate devices in group 2. Therefore, the first network element sends specific preamble sequence 3 to devices in group 1 and specific preamble sequence 6 to devices in group 2. The devices in group 1 then activate themselves and receive the target channel. After receiving the target channel, they send backscatter signals to the first network element. The devices in group 2 then deactivate themselves.

[0462] By adopting a solution of using a leading sequence to activate or deactivate a device, a specific leading sequence can be used to activate or deactivate a certain device, a certain type of device, or all devices, which facilitates the first network element to control the activation or deactivation status of the device, and also helps the device enter the activation or deactivation state as needed, which can save the power consumption of the device.

[0463] Example 2: The device identifier carried by the target channel implicitly indicates the broadcast type

[0464] The first network element sends a target channel to the device, where the target channel includes at least one of the following formats or types:

[0465] a first format or type for sending or receiving system information;

[0466] a second format or type for controlling the transmission or reception of information;

[0467] a third format or type for transmitting or receiving data information;

[0468] A fourth format or type for sending or receiving short messages;

[0469] A fifth format or type used for sending or receiving long messages.

[0470] In this example, specifically:

[0471] The device identifier in the target channel is used to implicitly indicate the broadcast type of the target channel. On the one hand, the device identifier in the target channel can be used to represent the identifier of the target device to which the target channel is to be sent. On the other hand, the first network element implicitly indicates the broadcast type of the target channel through the device identifier carried in the target channel, including broadcast, multicast, or unicast:

[0472] Broadcast: Use a specific device identifier, including: using an all-0 device identifier, or an all-1 device identifier to indicate that the broadcast type of the target channel carrying the device identifier is broadcast.

[0473] Multicast: Use a device identifier in a specific format, including: A device identifier starting with 101010 indicates that the broadcast type of the target channel carrying the device identifier is multicast.

[0474] Unicast: Use a normal device identifier, including: using a device identifier that is not used to indicate broadcast and multicast to indicate that the broadcast type of the target channel carrying the device identifier is unicast.

[0475] As shown in Figure 10, the specific process is as follows:

[0476] The first network element determines to send a broadcast signal with a device identifier of all 0s; the first network element sends a target channel to the first device and the second device; the first device and the second device respectively receive the target channel, and the first device and the second device respectively send a backscatter signal to the first network element.

[0477] By adopting a scheme of implicitly indicating the broadcast type of the target channel using a device identifier, a specific device identifier can be used to implicitly indicate the broadcast type of the target channel, which makes it easier for the first network element to indicate to the device whether the target channel is broadcast, multicast or unicast, and also helps the device determine whether it needs to receive the target channel based on the indication, which can save signaling overhead and device power consumption.

[0478] Example 3: The target channel contains two formats or types

[0479] The first network element sends a target channel to the device, where the target channel includes at least one of the following formats or types:

[0480] a first format or type for sending or receiving system information;

[0481] a second format or type for controlling the transmission or reception of information;

[0482] a third format or type for transmitting or receiving data information;

[0483] A fourth format or type for sending or receiving short messages;

[0484] A fifth format or type used for sending or receiving long messages.

[0485] In this example, specifically:

[0486] The target channel contains a first format or type for sending or receiving system information and a second format or type for sending or receiving control information.

[0487] That is, based on the target channel type or format field in the target channel, the target channel can be divided into two formats or types: a first format or type for sending or receiving system information, and a second format or type for sending or receiving control information. This facilitates the first network element to send the first format or type for sending or receiving system information, or the second format or type for sending or receiving control information, to the device according to different scenarios and requirements.

[0488] The applicable scenario is as follows: The first network element first sends system information to all devices, globally transmitting global configuration parameters. The devices receive the system information and obtain the global configuration parameters. Then, the first network element sends control information to specific devices, transmitting device-specific control commands. The specific devices receive the control information and obtain the device-specific control commands.

[0489] A design scheme in which the target channel includes two formats or types is adopted. The first network element can send target channels of different formats or types according to the scenario or requirements, and the first network element can also indicate through the target channel format or type field whether the specific type of the target channel is the first format or type for sending or receiving system information, or the second format or type for sending or receiving control information, thereby facilitating the device to receive the target channel according to the target channel format or type field.

[0490] Example 4: The target channel contains three formats or types

[0491] The first network element sends a target channel to the device, where the target channel includes at least one of the following formats or types:

[0492] a first format or type for sending or receiving system information;

[0493] a second format or type for controlling the transmission or reception of information;

[0494] a third format or type for transmitting or receiving data information;

[0495] A fourth format or type for sending or receiving short messages;

[0496] A fifth format or type used for sending or receiving long messages.

[0497] In this example, specifically:

[0498] The target channel contains a first format or type for sending or receiving system information, a second format or type for sending or receiving control information, and a third format or type for sending or receiving data information.

[0499] That is, based on the target channel type or format field in the target channel, the target channel can be divided into three formats or types: a first format or type for sending or receiving system information, a second format or type for sending or receiving control information, and a third format or type for sending or receiving data information. This facilitates the first network element to send the first format or type for sending or receiving system information, the second format or type for sending or receiving control information, or the third format or type for sending or receiving data information to the device according to different scenarios and requirements.

[0500] Applicable scenarios: The first network element first sends system information to all devices, globally transmitting global configuration parameters. The devices receive the system information and obtain the global configuration parameters. Then, the first network element sends control information to a specific device, transmitting device-specific control commands. The specific device receives the control information and obtains the device-specific control commands. Alternatively, the first network element sends data information to a specific device, transmitting device-specific data information. The specific device receives the data information and obtains the device-specific data information.

[0501] A design scheme in which the target channel includes three formats or types is adopted. The first network element can send target channels of different formats or types according to the scenario or requirements, and the first network element can also indicate through the target channel format or type field whether the specific type of the target channel is a first format or type for sending or receiving system information, or a second format or type for sending or receiving control information, or a third format or type for sending or receiving data information, thereby facilitating the device to receive the target channel according to the target channel format or type field.

[0502] Example 5: The target channel contains four formats or types

[0503] The first network element sends a target channel to the device, where the target channel includes at least one of the following formats or types:

[0504] a first format or type for sending or receiving system information;

[0505] a second format or type for controlling the transmission or reception of information;

[0506] a third format or type for transmitting or receiving data information;

[0507] A fourth format or type for sending or receiving short messages;

[0508] A fifth format or type used for sending or receiving long messages.

[0509] In this example, specifically:

[0510] The target channel contains a first format or type for sending or receiving system information, a second format or type for sending or receiving control information, a third format or type for sending or receiving data information, and a fourth format or type for sending or receiving short messages.

[0511] That is, according to the target channel type or format field in the target channel, the target channel can be divided into four formats or types: a first format or type for sending or receiving system information, a second format or type for sending or receiving control information, a third format or type for sending or receiving data information, and a fourth format or type for sending or receiving short messages. This facilitates the first network element to send the first format or type for sending or receiving system information, the second format or type for sending or receiving control information, the third format or type for sending or receiving data information, or the fourth format or type for sending or receiving short messages to the device according to different scenarios and requirements.

[0512] The applicable scenario is as follows: The first network element first sends system information to all devices to globally transmit global configuration parameters. The devices receive the system information and obtain the global configuration parameters. Then, the first network element sends control information to a specific device to transmit device-specific control commands. The specific device receives the control information and obtains the device-specific control commands. Alternatively, the first network element sends data information to a specific device to transmit device-specific data information. The specific device receives the data information and obtains device-specific data information. Alternatively, the first network element sends a short message to all devices to transmit a public control command. All devices receive the short message and obtain a public control command (for example, asset inventory).

[0513] A design scheme in which the target channel includes four formats or types is adopted. The first network element can send target channels of different formats or types according to the scenario or requirements, and the first network element can also indicate through the target channel format or type field whether the specific type of the target channel is the first format or type for sending or receiving system information, or the second format or type for sending or receiving control information, or the third format or type for sending or receiving data information, or the fourth format or type for sending or receiving short messages, thereby facilitating the device to receive the target channel according to the target channel format or type field.
